Development characteristics and oil-gas geological significance of slope break zone of Xujiahe Formation in Sichuan Basin

  • 摘要: 前人针对断陷盆地坡折带开展了大量研究,但前陆盆地前渊向前缘隆起方向坡度较缓,大型构造欠发育,地形起伏小,坡折带研究较少。四川盆地晚三叠世须家河组四、五段沉积时期发育前陆盆地,学者们已关注到泸州—开江古隆起西侧川中—川西地区缓坡坡折带对沉积岩相的控制,但其他相关研究较少。通过对四川盆地地震反射剖面坡折带构造解释,结合区域地质已有成果,采用颗粒流数值模拟方法,厘清了川中—川西地区坡折带类型,以及坡折带与重力滑动构造之间的关系,分析了与重力滑动构造相关的新型油气圈闭特征。研究获得如下认识:(1)研究区发育断裂坡折带,以坡折带为界,东、西两侧各发育一套重力滑动形成的“前挤后拉”构造组合,构造变形强度弱于被动大陆边缘重力滑动构造;(2)研究区构造坡折带边缘断裂控制沉积相与砂体类型;(3)缓坡带重力滑动构造拉张区正断层下盘上升形成同沉积背斜发育的砂岩,与同期断陷内富有机质泥岩侧接,形成“旁生侧储”型油气藏;(4)陡坡带重力滑动形成的须五段同沉积背斜,被翼部泥岩以及滑动构造结束后沉积的泥岩所围限,形成源内砂体输导成藏;(5)与重力滑动构造相关的同沉积背斜油气藏是源内成藏新类型,研究区须五段可能存在平行坡折带NE向展布的此类油气藏。
